Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a straddle-type vehicle.
The present invention relates to an installation mode of a spare tire. [Prior Art] In a saddle-ride type four-wheeled vehicle for running on uneven terrain, tires are easily damaged due to the running conditions, and therefore, provision of spare tires is indispensable. In addition, the above spare tire,
For reasons such as easy attachment / detachment, it is usually mounted on a carrier behind the seat, or on the front of the vehicle body. By the way, since installing a spare tire requires a large space, there is an inconvenience that mounting space other than the above spare tire on the front and rear of the vehicle body is limited. Was. Further, when a heavy spare tire is mounted on the carrier, the weight of the vehicle becomes high, which may adversely affect running stability. [Object of the Invention] The present invention has been made in view of the above circumstances, and provides a straddle-type vehicle that can secure a sufficient mounting space for equipment around a vehicle body and can lower the vehicle center of gravity. Aim. According to the present invention, the left and right front wheels and the left and right rear wheels are supported on the front and rear portions of the vehicle body frame,
A straddle-type vehicle in which an engine is mounted at a central portion in a front-rear direction between a front wheel and a rear wheel of a body frame, and a driver straddles a seat installed above and behind the engine and steers the front wheels. The front part and the rear part are respectively formed to be bent upward with the spare tire stored in the center part, and the front part is pivotally supported by the vehicle body frame in a manner capable of swinging with respect to the vehicle body frame. The above object is achieved by disposing a spare tire storage rack whose rear portion is removably fastened to and supported by the vehicle body frame at the bottom of the vehicle body frame below the engine. Examples Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows a straddle-type four-wheeled vehicle as a straddle-type vehicle according to the present invention. The saddle-ride type four-wheeled vehicle 1 includes a body frame 100 that supports a front wheel 2, a rear wheel 3, an engine 4, and the like. The body frame 100 is a front frame that is bolted to a front portion of the engine 4. 10; a center frame 20 bolted to the rear of the engine 4; an upper frame 30 and a lower frame 40 spanned between the two frames 10 and 20 and bolted; The engine 4 is configured to be mounted at the center of the body frame 100. In the drawings, reference numeral 6 denotes a water tank, 7 denotes an air cleaner, 8 denotes a fuel tank, and 9 denotes a seat. The rear frame 50 has seat rails.
A rear wheel 61 is mounted on the rear rail 61 via a bracket 62. As clearly shown in FIG. 1, a spare tire storage rack 70 (hereinafter, referred to as a rack 70) is provided below the engine 4. As shown in FIG. 2, the rack 70 has a pair of side pipes 71, 72 extending along the front-rear direction of the vehicle body linked via cross pipes 73, 74, 75, and 76. 74 is provided with a spare tire fixing block 77, and the cross pipes 73, 7
5 is provided with spare tire positioning plates 78, 79. As described above, the central portion of the spare tire storage rack 70 is configured to be able to store the spare tire 90 (see FIG. 1), and furthermore, a pair of side pipes 71, 72 constituting the spare tire storage rack 70. The front end portion (front portion) and the rear end portion (rear portion) are bent upward as is clear from the drawing. Furthermore, the above side pipe 7
A hinge pipe 80 is provided between the front ends of the first and second 72, and this pipe 80 is pin-connected to the bottom of the front frame 10 as shown in FIG. As a result, the rank 70 can freely swing between the tire storage position indicated by the solid line and the tire open position indicated by the chain line. Further, brackets 71a and 72a for fixing the rack are formed at the rear ends of the side pipes 71 and 72, respectively.These brackets 71a and 72b are fixed to the rear frame 50 by screws 85, The rack 70 is occupied and fixed at the tire storage position (solid line). The spare tire 90 for the front wheel is placed on the rack 70 occupying the open position, and the spare tire 90 is fixed to the rack 70 by screwing a fixing bolt (not shown) to the fixing block 77, Next, by swinging the rack 70 upward and fixing it to the rear frame 50 with the screws 85, the spare tire 90 is stored and held immediately below the engine 4. At the time of tire replacement, the screws 85 may be removed to bring the rack 70 to the open position, and the spare tire 90 may be taken out of the rack 70. In the present embodiment, the spare tire for the front wheel is stored below the engine, but it is of course possible to store the spare tire for the rear wheel. [Effects of the Invention] As described above in detail, according to the straddle-type vehicle according to the present invention, the spare tire storage rack is disposed below the engine and the spare tire is stored and held here. The space around the vehicle body can be prevented from being occupied by spare tires, thereby making it possible to secure a sufficient space for mounting equipment. Also,
By locating the spare tire below the engine, it is possible to lower the center of gravity of the vehicle body, improve running stability, and prevent the damage to the bottom of the engine because the spare tire serves as a so-called engine guard. It is also possible. Further, according to the straddle-type vehicle according to the present invention, the front part of the spare tire storage rack is pivotally supported by the vehicle body frame, and the rear part is fastened and supported to the vehicle body frame via the screw, so that the screw can be attached and detached. The spare tire storage rack can be easily opened and closed by the operation, so that the operation of inserting and removing the spare tire can be easily performed. Also, the front part and the rear part of the spare tire storage rack are each formed to be bent upward, and the shaft support and the fastening support for the body frame are positioned higher than the central part where the spare tire is stored, Damage to the shaft support and the fastening support due to unevenness of the road surface, jumping stones and the like can be suppressed as much as possible.
